When at least one of a value a detected output current to a magnet (10) and a magnet load defined by the following formula (1) is equal to or larger than a threshold value predetermined for the value of the detected output current or a threshold value predetermined for the magnet load, a controller (3) constituting a control device (100) outputs, to a control circuit (2), a command to decrease voltage applied to the magnet (10) from next attracting operation. Magnet load = excitation ratio × I × V Excitation ratio: excitation time/(excitation time + non-excitation time) I: value of the output current V: voltage applied to a lifting magnet
